I need to bribe our admins (OPs) on my paid work to try FreeBSD instead of Solaris on new servers :) We are processing huge amount of multicast streams (up to 2.5-3Gbit/s with 500-1000 bytes packets) and have difficulties not to lose any packets on Solaris :) They tried Linux without success, but FreeBSD is unknown to them. One problem for FreeBSD is that our applications are Java-based... Problems are not in Java, but in Intel drivers (igb / ixgb in FreeBSD terms), which sometimes lose packets with "buffer is not available" diagnostics when consumer is heavily-multithreaded. --=20 // Black Lion AKA Lev Serebryakov <lev@serebryakov.spb.ru>
